Design and Implementation of High-speed X-ray Nondestructive Detector
摘要
Abstract
A high-speed X-ray nondestructive detector is designed in this paper. The principle of X-ray nondestructive detection is analyzed, and a general system scheme of the high-speed X-ray nondestructive detector is proposed. The Virtex-4 series Fx12 FPGA chip is used to design its hardware circuit, the PowerPC405 embedded system is developed, the high-speed image processing algorithm is applied to compile its processing software, and TCP/IP protocol is employed to compile the correspondence software, to realize high-speed X-ray signal gathering, processing and transmission. The experimental result indicated that the detector can be applied to the long-distance and on-line nondestructive detection of product line with Steel Wire Ropes in correlative industry field, such as mines, ports and wharfs. The running rate of the conveyer belt could achieve 6m/s when the survey width of the detector is 1.6 m.
